Sketch in Weldment?

In a standard IAM you can create a Sketch, but
in a Weldment, you can't in the main IAM enviroment. Did something change, or
was this functionality never there.

Work-a-round is to have a uncomsumed sketch, but
this requires a separate IPT file.

Sketches are enabled when Preparations or Machining
is active.

But you can't have a sketch in the main IAM
enviroment the same as a standard IAM non-weldment

I believe the sketches are restricted to those
environments In elements because you can't create features at the top
level. What are you using the sketch for? I can add this to our database, but it
helps if I have documentation on the workflow it is supposed to
support..

Loren,

 

I appriciate this is an old post, but I got a good reason to have a sketch in a weldment.

 

To help place a work feature

 

Take a hollow hemisphere

 

Make a hole through the shell that is off-centre from the middle, but parallel to the centre line

 

You have curves in all three dimensions, so placing work planes accurately become difficult

 

I now need a work point that is in the centre of the hole and aligned with the outside of this hemispherical shell

 

I also want to put it in with the least number of work features to keep the file size to a minimum.

 

I would put a work axis down the hole and a work plane between the centre work plane and the one down the hole.

 

Next I would put a sketch on the work plane a project the geometry

 

Where the sketch geometry crosed the user work axis I would put a work point.

 

I'm open to any better suggestions as well

 

TIA

Sounds like the same thing I'm trying to do.

 

Workflow is:

 

Open weldment

Create specific planes for nozzles on tank head ( for repositing on head later)

Place tank head from standards library

Start machining

Create first cut for vessel inlet flange

Create sketch on vent nozzle plane at desired angle

This is to produce a hole cut thru the tank head (for locating the pipe/flange later)

When trying to create an axis and point the workflow comes to a screeching halt

Inventor 2013 will not allow me to perform those tasks

 

This workflow is more desirous than copying/renaming the standard tank head just to make cutouts.

Then placing that .ipt into a weldment.iam.  What would be the point of having a standard tank head if you can't perform these basic tasks.
